The Prusa Pro HT90 Drybox is a storage and feeding station designed to maintain technical filaments in a low-humidity environment during FDM production phases. Developed for moisture-sensitive materials, it limits extrusion behaviour variations caused by water absorption, particularly for technical polymers used in industrial environments.
The system enables direct feeding of the printer from the sealed enclosure to preserve filament stability throughout the print cycle. The design is optimised for prototyping workshops, R&D environments and production applications requiring controlled extrusion regularity with technical materials.
Humidity management
The Drybox uses a passive humidity control system combined with a hermetic compartment for spool storage. This configuration reduces the risks of bubbling, surface defects and layer weakening caused by moisture absorbed by certain hygroscopic thermoplastics.
It is particularly suited to filled filaments, high-temperature polymers and materials requiring stable storage conditions between print cycles. Spool access remains compatible with continuous use in a production environment.
Implementation in a professional environment
The structure is designed for direct integration into a professional FDM additive manufacturing workflow. Filament feeding to the printer is performed without intermediate handling to minimise exposure to ambient air. The solution can be used both during prototyping and for small-series production requiring more stable material conditions.
